Where do you check "raid auto-detect" from fdisk?
fdisk (util-linux-ng 2.17.2)
fdisk -l /dev/md/OneTB-RAID1-PV
Disk /dev/md/OneTB-RAID1-PV: 1000.2 GB, 1000202043392 bytes
255 heads, 63 sectors/track, 121600 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

Also note that fdisk -l /dev/md/imsm0 returns nothing....
